These standards (referred to as the Subpart CC standards) are designed to further reduce organic air emissions from hazardous waste management activities. Environmental Protection Agency (EPA) issued the second phase of the organic air emission standards for hazardous waste treatment, storage, and disposal facilities (TSDFs) and hazardous waste generators in December 1994. This paper presents treatability test results for a stacked- tray air stripper conducted at LLNL and compares them to the vendor`s modeling software = , This extensive oversight makes it necessary to accurately predict field treatment performance at new extraction locations to ensure compliance with all requirements prior to facility activation. National laboratories are also subject to scrutiny by the public and other government agencies.

These agencies set discharge limits, require performance monitoring, and assess penalties for non-compliance. System operations at LLNL are strictly regulated by the California and federal Environmental Protection Agencies (Cal/EPA and EPA), the Bay Area Air Quality Management District (BAAQMD), the California Regional Water Quality Control Board (RWQCB) and the Department of Toxic Substances Control (DTSC). In stacked-tray air strippers, contaminated water is aerated while it flows down through a series of trays. Many P&T remediation systems at VOC sites rely on air stripping technology because VOCs are easily transferred to the vapor phase. In P&T operations, contaminated ground water is pumped from wells, treated above ground, and discharged.

A common strategy for hydraulic containment and mass removal at VOC contaminated sites is `pump and treat (P&T)`.
